A series of dirhodium(II,II) paddlewheeel complexes of the type cis-[Rh-2(mu-DTolF)(2)(mu-L)(2)] [BF4](2), where DTolF = N,N’-di(p-tolyl)formamidinate and L = 1,8-naphthyridine (np), 2-(pyridin-2-yl)-1,8-naphthyridine (pynp), 2-(quinolin-2-yl)-1,8-naphthyridine (qnnp), and 2-(1,8-naphthyridin-2-yl)quinoxaline (qxnp), were synthesized and characterized. These molecules feature new tridentate ligands that concomitantly bridge the dirhodium core and cap the axial positions. The complexes absorb light strongly throughout the ultraviolet/visible range and into the near -infrared region and exhibit relatively long-lived triplet excited-state lifetimes. Both the singlet and triplet excited states exhibit metal/ligand-to-ligand charge transfer (ML-LCT) in nature as determined by transient absorption spectroscopy and spectroelectrochemistry measurements. When irradiated with low -energy light, these black dyes are capable of undergoing reversible bimolecular electron transfer both to the electron acceptor methyl viologen and from the electron donor p-phenylenediamine. Photoinduced charge transfer in the latter was inaccessible with previous Rh-2(II,II) complexes. These results underscore the fact that the excited state of this dass of molecules can be readily tuned for electron-transfer reactions upon simple synthetic modification and highlight their potential as excellent candidates for p- and n-type semiconductor applications and for improved harvesting of low -energy light to drive useful photochemical reactions.

In a article, author is Zhang, Yu, introduce new discover of the category.

The 1,8-naphthyridine and diiodine were selected as model molecules to investigate the possible effect of the strong N center dot center dot center dot I halogen bond on the electronic structures and properties of potential organic semiconductor building blocks. The N center dot center dot center dot I halogen bond in the crystal structure of the cocrystal formed between 1,8-naphthyridine and diiodine has an interaction energy of -21.41 kcal/mol. The cooperativity and anticooperativity between the strong halogen bond and other noncovalent interactions, including the hydrogen bond, tetrel bond and stacking interaction, were also studied in detail. The formation of the strong N center dot center dot center dot I halogen bond leads to the formation of the regularly layered structures of the cocrystal, which is a necessary condition for the organic semiconductor to conduct electrons or holes. On the other hand, the formation of the strong N center dot center dot center dot I halogen bond lowers both the energy of the lowest unoccupied molecular orbital of 1,8-naphthyridine and the energy gap of frontier molecular orbitals of 1,8-naphthyridine. These results clearly show that the strong halogen bond can be used as a cheap and effective tool for the design and synthesis of organic semiconductor materials.

Four new 2-amino-5,7-dimethyl-1,8-naphthyridine derivatives (1-4) possessing urea, amide-imidazolium salt, amide-azide, or amide-triazole moieties were synthesized in good to excellent yields by derivatization of 2-amino-5,7-dimethyl-1,8-naphthyridine. We examined their anion recognition abilities towards different anions such as fluoride, chloride, bromide, iodide, nitrate, dihydrogen phosphate, cyanide, hexafluorophosphate, perchlorate, hydrogen sulphate and acetate by H-1 NMR and UV-Vis spectroscopy. Among various 2-amino-5,7-dimethyl-1,8-naphthyridine derivatives, only 1a and 2 showed spectroscopic and colorimetric change when treated with fluoride ions among other anions. The F- ions first established a hydrogen-bonding interaction with 1a to give the most stable 1:1 complex and then, after addition of a second equivalent, the F- ions induced urea deprotonation due to the formation of HF2-. Moreover, 2 underwent deprotonation of amide -NH proton after the addition of 1 equiv. of fluoride ions. The action of the probes was thoroughly investigated by DFT calculations that also supported the H-bonding induced deprotonation sensing mechanism.

The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Mukherjee, Sanjukta, once mentioned the application of 5089-22-5, Name is 1,4-Bis(benzo[d]oxazol-2-yl)naphthalene. Now introduce a scientific discovery about this category, Category: naphthyridines.

Cyclophane-containing bis(2-amino-1,8-naphthyridine) moieties attached to variable linkers at the C2-position (linker B) were synthesized as cyclic mismatch-binding ligands (CMBLs). Ring-closing metathesis (RCM) is used as a key step for the introduction of double bonds at the linker B. Decreasing the size of the linker of the substrate, formation of the RCM products with an increasing trans/cis (E/Z) ratio was observed with moderate to high overall yields. Concentration-dependent fluorescence spectra were observed for CMBLs with longer linkers (n=3), whereas concentration-independent spectra were observed for CMBLs with shorter linkers (n=2 and/or 1) with a marked exception of the E-alkene 6a. Concomitant changes in the absorption as well as in the fluorescence spectra were also observed for the CMBLs with an increasing hydrophobicity of the solvent. Absorption and fluorescence spectra of the CMBLs in solutions containing 99-100% methanol resembled to that of the monomer. The binding behavior of these CMBLs with repeat DNA structures was investigated by using a surface plasmon resonance (SPR) assay and circular dichroism (CD) spectra. The cyclic E-alkenes 1a (n=3) and 3a (n=2) show an orthogonal binding relationship with d(CCTG)(9) and d(CAG)(9). However, the selectivity for the cyclic Z-alkenes increased with decreasing the length of the linker from compound 2b (n=3) to compound 7b (n=1). These compounds display a large molecular diversity, which allowed the tuning of the binding affinity and selectivity of the CMBLs by varying the linkers towards various biologically significant repeat DNA structures.

In a document, author is Pineiro-Lopez, Lucia, introduce the new discover, Electric Literature of 3147-75-9.

Two new 3D spin-crossover (SCO) Hofmann-type coordination polymers {Fe(2,6-naphthy)[Ag(CN)(2)][Ag-2(CN)(3)]} (1; 2,6-naphthy = 2,6-naphthyridine) and {Fe(2,6-naphthy)-[Au(CN)(2)](2)}center dot 0.5PhNO(2) (2) were synthesized and characterized. Both derivatives are made up of infinite stacks of {Fe[Ag(CN) (2)](2)-[Ag-2(CN)(3)]}(n) and {Fe[Au(CN)(2)](2)}(n) layered grids connected by pillars of 2,6-naphthy ligands coordinated to the axial positions of the FeII centers of alternate layers. The in situ generated [Ag-2(CN)(3)](-) linkers define wide rectangular windows that favor the interpenetration of three identical 3D networks, strong argentophilic interactions between them, and the generation of a densely packed structure without accessible void spaces. In contrast, the smaller rhombus-shaped window in 2 affords a structure made up of doubly interpenetrated 3D networks with strong aurophilic interactions between them and accessible voids partially occupied by nitrobenzene molecules. Compound 1 displays a relatively abrupt two-step SCO in the temperature interval 150-215 K, whereas 2 features an incomplete one-step SCO behavior (T-1/2 = 166 K) that extends over 150 K.

In a patnet, author is Sirakanyan, Samvel N., once mentioned the new application about 286961-14-6.

Background and Objective: Continuing our studies in the field of a new rearrangement in the 2,7-naphthyridine series, the synthesis and rearrangement of mono-2 and di-amino derivatives 3 of 2,7-naphthyridine was carried out. Taking into account the wide range of pharmacological activities of pyrazole derivatives the synthesis of some 3-amino-1-(3,5-dimethyl-1H-pyrazol-1-yl)-2,7-naphthyridines 8 and of pyrazolo[3,4-c]-2,7-naphthyridine 12 was described. Methods: Compounds 2 were reacted with amines furnishing the relevant rearrangement products 4. Starting from the 7-benzyl-3-chloro-1-hydrazino-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 6 and 5-hydrazino-6,7,8,9- tetrahydro-3H-pyrazolo[3,4-c]-2,7-naphthyridin-1-amine 12 the 7-benzyl-3-chloro-1-(3,5-dimethyl-1H-pyrazol- 1-yl)-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 7 and 3,5-dimethyl-1H-pyrazol-1-yl-9,11-dimethylpyrimido[1′, 2′: 1,5] pyrazolo[3,4-c]-2,7-naphthyridine 13 were synthesized, via the Knorr synthesis of pyrazoles. Results: The syntheses of 2-benzyl-6,8-diamino-3,4-dihydro-2,7-naphthyridin-1(2H) ones 4 deriving from the rearrangement of compounds 2 and/or 3 were performed. By reaction with benzylamine compound 2a or 3g gave the unexpected formation of N, 7-dibenzyl-8-(benzylimino)-3-pyrrolidin-1-yl-5,6,7,8-tetrahydro-2,7-naphthyridin- 1-amine 5: in fact, the rearrangement was followed by condensation between the C-1 carbonyl group of the 2,7-naphthyridine ring and the benzylamine. Starting from the 7-benzyl-3-chloro-1-(3,5-dimethyl-1H- pyrazol-1-yl)-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 7 the relevant 3-amino-7-benzyl-1-(3,5-dimethyl- 1H-pyrazol-1-yl)-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitriles 8 were obtained. In harsh experimental conditions the nucleophilic substitution of the 1-pyrazolyl residue took place with formation of 7-benzyl- 1,3-bis[(2-hydroxypropyl) amino]-5,6,7,8-tetrahydro-2,7-naphthyridine-4-carbonitrile 10. Moreover, compound 7 reacted with hydrazine hydrate giving the pyrazolo[3,4-c]-2,7-naphthyridine 12, which, in turn, furnished a new tetra-heterocyclic system: 3-benzyl-5-(3,5-dimethyl-1H-pyrazol-1-yl)-9,11-dimethyl-1,2,3,4-tetrahydropyrimido[1′, 2′: 1,5] pyrazolo[3,4-c]-2,7-naphthyridine 13. Conclusion: Replacement of methyl group on piperidine ring of 2,7-naphthyridine system with the benzyl one led to new results. Reaction of compound 2a or 3g with benzylamine brought to an unexpected formation of N, 7-dibenzyl-8-(benzylimino)-3-pyrrolidin-1-yl-5,6,7,8-tetrahydro-2,7-naphthyridin-1-amine 5. The reactivity of 7-benzyl-3-chloro-1-(3,5-dimethyl-1H-pyrazol-1-yl)-2,7-naphthyridine 7 with nucleophiles was investigated, observing the unexpected substitution of the 1-pyrazolyl residue.

Ferrocenylamido-naphthyridine conjugates [{(5,7-dimethyl-1,8-naphthyridin-2-yl)amino} carbonyl] ferrocene (L-1) and 1,1′-bis[{(5,7-dimethyl-1,8-naphthyridin-2-yl) amino} carbonyl] ferrocene (L-2) have been synthesized. Reaction of L-1 with [Cu(CH3CN)(6)][ClO4](2) affords [Cu(L-1)(2)][ClO4](2) (1) demonstrating tridentate coordination of the ligand utilizing naphthyridine (NP) nitrogens and carbonyl oxygen. Hydroxo-bridged neutral dirhenium(I) compound [K subset of {{Re(CO)(3)}(2)(mu-OH)(Fc(CONHNP)(CO (N) over bar NP))(2)}] (2) is reported in which the amido-NP arm of L-2 chelates a Re-I, and a K+ ion is encapsulated in a six-coordinate environment rendered by four NP nitrogens and two carbonyl oxygens involving all four arms of two L-2 ligands. Selective and reversible binding of K+ ion by the organometallic host has been recognized from electrochemical and fluorescence experiments. Partial hydrolysis of L-2 has provided a neutral metallamacrocycle [{Re(CO)(3)}(2){Fc(CO2)(CONHNP)}(2)] (3) consisting of alternate Fc and Re(CO)(3) units linked by carboxylate and amide-NP bridges. The rotational freedom of the ferrocenyl rings, the flexibility of the amide linker and the multi-site coordination of the ligands are demonstrated in the molecular structures of compounds 1-3.
